October hydrant flushing in Orono could cause water discoloration, but water is safe

ORONO, Maine — The Orono-Veazie Water District will flush hydrants in Orono beginning Oct. 1 and continuing for several weeks, the district announced Thursday.

Temporary signs will be posted in neighborhoods the day before crews begin working on hydrants in those areas.

The district flushes its hydrants twice a year. The process involves sending a large volume of water through the hydrant, increasing water flow in the pipeline and removing mineral deposits from the water system.

The scouring of the inside of the pipes can cause discoloration of residents’ tap water as the sediment is flushed out, but the water still will be drinkable.

“There is no health hazard associated with the discolored water,” a water district press release states.

To avoid getting discolored water at all, the district suggests residents not turn on their tap or run appliances that use water while flushing is occurring in their area. That will prevent discolored water from entering household plumbing, according to the district.

Doing laundry while flushing is taking place could stain fabrics.

“If you encounter discolored water following hydrant flushing, run the cold water taps throughout your home for 5-10 minutes or until water clears,” the press release suggests.
